IMPROVEMENT IN ROCK-BREAKING MACHINES.'

Specification forming part of Lettrrs Patent No. 4],.585, dated February 9, 1864.

To all whom it may concern:

Be it known that I, JAMES B. WAYNE, of Detroit, in the county of Wayne, in the State of Michigan, have invented a new and useful Improvement in the Manner of Gripping Rods used for Rock-Breaking, Stamping, or Crushing Purposes; andI do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings,and to theletters of reference marked thereon.

Figure 1 is a perspective view of model of machine. Fig. 2 is a section of sleeve. Fig. 3 is a side view of link. Fig. 4 is a top view of link. Fig. 5 is an end View of the guide. Fig. 6 is a longitudinal section of corrugated rod and corrugated die.

A, Fig. 1, is the lifting-cam; b, the lowering-down cam; o, the sleeve; (1, the link; d, the pin in link cl,- e, the roller on end of link d. fis the guide; 9 g, the cushions, of indiarubber, in slot 0, one above and onebelow the pin 01; h,the corrugated die set free in an opening in the sleeve c', i, the rod or stem; is, a The motion of the cam A on its axis acts against the roller 6 on end of link d, and produces a horizontal motion to the corrugated die it against the corrugated part of the rod z, pressing firmly against it, causing the pin 01 to rest against the yielding cushionsgg until the corrugations are firmly locked together, and then during the time the rod is being lifted it pulls the link d against the inside of slot 0 in sleeve 0. When the cam A has lifted the stem 2', with sleeve 0, to its utmost limit and passed by the center of the roller 0, the link d becomes free to drop and the corrugated die h is forced back by the weightof the descending rod t, so as to be ready for succeeding lift at the next revolution of the cam A. When the sleeve 0 has thus become free on the rod 2', the loweringdown cam presents itself under the roller k, and allows the sleeve 0 to descend on the rod e in an easy manner, so as to be ready for anotherlift of cam A in its revolution.

I know that machines are nowin use breaking rock and crushing ores. I therefore do not claim the machine as a whole; but

What I do claim are improvements, as follows:

' 1. The use of a separateloweringdown cam, b, Fig. 1, substantially as described, for lowering down the clutch c.

2. The link 01, Fig. 1, or its equivalent, in connection with the sleeve 0, one end pressing against the die h in an upward direction and the other end fitted with apin, d, resting on cushions g g, of india-rubber, or their equivalent, and pulling against the sleeve'c, thereby'avoiding any outward or breaking strain on sleeve 0, but producing an inward pressure at each end of link 01, substantially as described.

3. The use of roller e, Fig. 1, in connection with link d and lowering down cam b, thereby destroying the tendency to friction, as is the casein working against a flat surface as in use now.

4. The use of inclined guide f, Fig. 5, thereby allowing the rod or stem i, Fig. 1, to move on its axis at every upward motion of the same by action of cam A, substantially as de scribed.

5. The use of corrugated die h, Fig. 6, in connection with sleeve 0 and link d, Fig. 1, substantially as described.
